DESCRIPTION
     ewfacquire	is a utility to	acquire	media data from	a source and store it
     in	EWF format (Expert Witness Compression Format).	 ewfacquire acquires
     media data	in a format equivalent to EnCase and FTK imager, including
     meta data.	Under Linux, FreeBSD, NetBSD, OpenBSD, MacOS-X/Darwin
     ewfacquire	supports reading directly from device files. On	other plat-
     forms ewfacquire can convert a raw	(dd) image into	the EWF	format.

     ewfacquire	is part	of the libewf package.	libewf is a library to access
     the Expert	Witness	Compression Format (EWF).

     source the	source file(s) or device

     The options are as	follows:

     -A	codepage
	     the codepage of header section, options: ascii (default), win-
	     dows-874, windows-932, windows-936, windows-949, windows-950,
	     windows-1250, windows-1251, windows-1252, windows-1253, win-
	     dows-1254,	windows-1255, windows-1256, windows-1257 or win-
	     dows-1258

     -b	number_of_sectors
	     the number	of sectors to read at once (per	chunk),	options: 16,
	     32, 64 (default), 128, 256, 512, 1024, 2048, 4096,	8192, 16384 or
	     32768

     -B	number_of_bytes
	     the number	of bytes to acquire

     -c	compression_values
	     specify the compression values as:	level or method:level compres-
	     sion method options: deflate (default), bzip2 (bzip2 is only sup-
	     ported by EWF2 formats) compression level options:	none (de-
	     fault), empty-block, fast or best

     -C	case_number
	     the case number (default is case_number)

     -d	digest_type
	     calculate additional digest (hash)	types besides md5, options:
	     sha1, sha256

     -D	description
	     the description (default is description)

     -e	examiner_name
	     the examiner name (default	is examiner_name)

     -E	evidence_number
	     the evidence number (default is evidence_number)

     -f	format
	     the EWF file format to write to, options: ewf, smart, ftk,	en-
	     case1, encase2, encase3, encase4, encase5,	encase6	(default), en-
	     case7, linen5, linen6, linen7, ewfx.

     -g	number_of_sectors
	     the number	of sectors to be used as error granularity

     -h	     shows this	help

     -l	log_filename
	     logs acquiry errors and the digest	(hash) to the log filename

     -m	media_type
	     the media type, options: fixed (default), removable, optical,
	     memory

     -M	media_flags
	     the media flags, options: logical,	physical (default)

     -N	notes
	     the notes (default	is notes)

     -o	offset
	     the offset	to start to acquire (default is	0)

     -p	process_buffer_size
	     the process buffer	size (default is the chunk size)

     -P	bytes_per_sector
	     the number	of bytes per sector (default is	512) (use this to
	     override the automatic bytes per sector detection)

     -q	     quiet shows minimal status	information

     -r	read_error_retries
	     the number	of retries when	a read error occurs (default is	2)

     -R	     resume acquiry at a safe point

     -s	     swap byte pairs of	the media data (from AB	to BA) (use this for
	     big to little endian conversion and vice versa)

     -S	segment_file_size
	     the segment file size in bytes (default is	1.4 GiB) (minimum is
	     1.0 MiB, maximum is 7.9 EiB for encase6 and encase7 format	and
	     1.9 GiB for other formats)

     -t	target
	     the target	file (without extension) to write to (default is im-
	     age)

     -T	toc_file
	     specify the file containing the table of contents (TOC) of	an op-
	     tical disc. The TOC file must be in the CUE format.

     -u	     unattended	mode (disables user interaction)

     -v	     verbose output to stderr

     -V	     print version

     -w	     zero sectors on read error	(mimic EnCase like behavior)

     -x	     use the chunk data	instead	of the buffered	read and write func-
	     tions.

     -2	secondary_target
	     the secondary target file (without	extension) to write to

     ewfacquire	will read from a file or device	until it encounters a read er-
     ror. On read error	it will	retry the number of retries specified. If
     ewfacquire	still is unable	to read	and, if	specified, it will zero	(wipe)
     the the remainder of the number of	sectors	specified as error granular-
     ity. If ewfacquire	should mimic EnCase it will zero all of	sectors	speci-
     fied as error granularity.

     Empty block compression detects blocks of sectors with entirely the same
     byte data and compresses them using the default compression level.

     The encase6 and encase7 format allows for segment files greater than 2
     GiB (2147483648 bytes).

EXAMPLES
     ewfacquire	can either image devices, (split) RAW image file(s) or optical
     disc (split) RAW image files.  ewfacquire will try	to detect device in-
     formation,	but results may	vary per platform.  In attended	mode (default)
     ewfacquire	will ask for the information it	requires.
